Our invention relates to improvements in portable hand-operated devicescr machines for driving glaziers points into window sashes, pictureframes, and the like, for the purpose of holding or assisting in holdingin place the panes of glass in said sashes, frames, etc., which machinescomprise magazines for the points and spring-pressed plungers forforcing the points into the wcod surrounding the glass.

One object of our invention is to produce a comparatively simple andinexpensive, but strong, durable, convenient, practical, and easilyoperated driver for glaziers points, wherein the plunger normally is inretracted position. Heretofore the plunger normal y is in advancedposition and is retracted and released by means of trigger mechanism,such mechanism is entirely done away with in the present driver. Y

Another object is to provide simple yet secure means for attaching thedriver plate to and detaching it from the plunger.

A further object is to furnish the driver with improved means for usingthe same in a t-ilted position, with the front end only on the glass andagainst the wood, and in a manner to enable the points to be driven invery close to the glass.

The driver consists of few parts which are easily assembled, and in caseof excessive wear or breakage can be readily removed and replaced withothers.

Other objects and advantages will appear in the course of the followingdescription;

l/Ve attain the objects and secure the advantages of our invention bythe mechanism illustrated in the accompanying drawings, in which- '40Figure 1 is a side elevation of a glaziers point driver which embodies apractical form of our invention; Fig. 2, longitudinal,

. Fig. 11, a side elevation of theparts shown in Fig. 10.

Similar reference characters designate similar parts throughout theseveral views.

The driver comprises a vertical member 1, herein termed a magazine, andusually made in two side sections riveted together, a support 2extending rearwardly from said magazine, a spring-pressed plunger 3mounted on said support and provided with a rearwardly extending andsomewhat upwardly inclined handle 5, a driver plate 6 secured to saidplunger, a wear plate which wear plate might be omitted, as willhereinafter be eX- plained, and a receiver plate 8.

lliithin the magazine 1 .are front and rear, vertical passages 9 and 10,respectively. rlhe passage 9 opens unrestrictedly through both ends,while the passage 10 may open at the .bottom the full diameter 'of thepassage, but

at the top is constricted. The passage 9 is in cross sectiondiamond-shaped and of a size to receive laziers oints such as those reresented at 11 in Fig. 2. v

vOrdinarily glaziers? points are with the aid of adhesive materialformed into sticks, in the manner well understood by those skilled inthe art, and the passage 9 is adapted to receive such a stick. f

Extending rearwardly from the magazine 1, a short distance abovethebottom thereof, is an interiorly screw-threaded lug or prot jection12 in which the forward end ofthe support 2 is received, said supportbeing eX- ternally screw-threaded to engage the threads in said lugs.'Thus the support 2 is rigidly held in a horizontal position. The backpart of the magazine 1 is taller than the front part of the same, andthere is a horizontal ledge 13 on each side of said magazine.

.In opposite sides of the magazine l, a short distance above the bottomthereof, are two indentations 14, and said magazine is bored back ofsaid indent-ations to receive a horizontal bolt 15. The wear plate 7 isformed with lateral projections or flanges 16-16, and with upwardlyextending side pieces 17 which have inwardly extending projections 18-18that enter the indentations lll. The side pieces 17 are also perforatedto receive the bolt 15, by means of which and a` nut 19 said side-piecesare rigidly attached to the magazine. The plate 7 extends beneath theopen bottom end of the passage 10, and opens v directly below the bottomend of the passage 9, the opening in said plate corresponding in sizeand shape with said last-named lpassage in cross section, and beingclearly shown .at 2O in Fig. 2. In other words, the opening in the plate7 is diamond-shaped and of a size to permit the points 11 to passthrough the same. The thickness of the plate 7 is approximately the sameas that of a point 11. The flanges 16 form supports and guides for theforward terminal portion of the driver plate 6, which plate is rolledupwardly and inwardly at the sides to form beads 21-21 to receivetherein such flanges.

The plate 8 is provided to receive the points y11 as they move down outof the passage 9,

under the influence of a follower 22, through the opening 20 in the wearplate 7, in front of the driver plate 6, and said plate is provided atthe sides with beads 23-23 that are adapted to receive within them thebeads 21 of the plate 6, and with ears 24-24 which are Vadapted to graspbetween them the side pieces 17. The projections 1S in the side pieces17 are formed by a punching process which leaves indentations to receiveprojections 2525 punched from or in the ears 24. Struck up from theplate 8 at the front end thereof are two protuberances 26, the height ofwhich equals the thickness of the plate 6. rl'hese protuberances preventthe plateA 3 from tilt-v ing upwardly at the front end and thus closingthe discharge opening between the plate 7 and said first-named plate.The front end of the plate 8 may be made concave, as shown at 27 in Fig.5, and the front-end portion of said plate on the bottom is beveled fromthe front edge downwardly and rearwardly, as represented at 28.

`When the plate 8 is in place, the front end of the sani-e is located ashort distance baclr of the front end of the plate 7.

The plate 8 receives the bottommost point 11 and retains it in positionin front of the driver plate 6 ready for the latter to force said pointinto a window or frame member. `llithout the receiver plate the points11 would escape proniiscuously and prematurely from the magazine.

In the center of the front-end portion of the driver Vplate 6 is aV-shaped notch 29 that corresponds in size and shape approximately withone-half of a point 11, and in said portion on each side of said notchis a recess 30. Obviousl if the plate 6 be forced forwardly, it carrieswith it the point 11 which is in front of the same. EachA recess 30 isin line with one of the protuberances 26, and thus enable the plate 6 tomake its full stroke without encountering said protuberances.

rllhe follower 22 is an inverted U-shaped member which forces the points11 through the opening 20 in the plate 7 onto the plate 8. One leg ofthe follower 22 is in the passage 9 and the other leg in the passage l0and at the bottom of the follower leg which is in the passage 10 is acollar 31, and interposed between said collar and an inwardly extendingpart at the top of said passage is a spring 32. The spring 32 tendsconstantly to force the follower 22 downwardly, and cause one leg 1l inthe passage 9, follow downwardly with said points as their numberdecreases, and cause them to be presented consecutively to the driverplate 6.

llhen it is desired to load the magazine with points, the exposed, upperportion of the follower 22 is grasped and said follower elevated againstthe resiliency of the spring 32 until the leg in the passage 9 is raisedout of said passage, swung on the other leg, and permitted to descendwith said firstnamed leg on the ledge 13 on one or the other side ofsaid magazine. Then a new stick of points is placed in the passage 9,and the follower 22 is returned to its former position, with the freeleg in the passage 9 on top of said points.

The plunger 3 adjacent to the forward end thereof has a downwardlyextending leg 33 at the bottom of which is a horizontal foot 34. rlheside edges of the foot 3a are curved to correspond with the flanges 16,and also to lit within the beads 21 of the driver plate G. rllhe rearend of the foot 34 at the bottoni extends downwardly to form a stop 35for the plate 6. The plate 6 is held against endwise movement by thestop 35 and a protuberance 36 struck up from said plate near therear endand received in an indentation in the bottom of the foot 34. There is anopening 37 in the plate 6 for vard of the foot 34 for the insertion ofan implement used to force said plate into place against the s top 35,and to detach said plate when occasion requires, the beads 21 beingsufficiently resilient to enable the to said foot and detachedtherefrom. Vhen the plate 6 is in place with the rear end against thestop 35, said plate isV prevented from moving kendwise independently ofthe foot 34, consequently said plate is carried with the plunger 3 inits forward and rearward movements, the plate then sliding between theplates plate thus to be secured 7 and 8. Normally the plate 6 is re- ,85thereof to bear on the points i tained with its front end in position toengage the bottommost point V11.

lVithin the plunger 3 is a chamber 52 open at the front end to receivethe support 2, and having in the rear end a central opening 37 in linewith the axis of the support 2. Tn the support 2 is a chamber 33 havingat the rear end a flange 39. A bolt 40 has at the front end a head 4lwhich is located in the chamber forward of the flange 39, and said boltextends through said flange and the chamber 52, and has a screw-threadedpart 42'that extends through the opening 37 to receive a nut 43 behindthe end of the plunger 3. The screw-threaded part 42 is smaller indiameterthan the main portion of the bolt 4() to form a shoulder whichbears against the front side of t ie rear end of the plunger 3,consequently, when the nut 43 is tightened, said end is tightly graspedbetween said -shoulder and said nut, and said bolt is thereby heldsecurely in place. ln the chamber 38 is a spring 44 interposed betweenthe inner end of the opening in the lug 12 and the bolt head 41.

Vhen the plunger 3 isv forced forwardly, the bolt 40 moves with saidplunger and compresses the spring 44, and, when the force behind saidplunger is removed, said spring expands and causes said bolt and with itthe plunger to move rearwardly, assuming that the front end of thedriver be held against a support which prevents the magazine 1 frommoving rearwardly. The plunger`3 in moving forwardly comes into Contactwith the lug 12 which limits such movement. The rearward movement of theplunger 3 is limited by the bolt head 41 when said head comes intocontact with the support ange 39. During the forward and rearwardmovements of the plunger 3, said plunger slides on the support 2 and thebolt 40 slides in the flange 39.

.The handle 5 is provided at the rea-r end with a knob 45 to be receivedin the palm, and

' forward of said knob with upper and under horns 46 to be graspedbetween the lingers, of the hand with which the driver is operated. Theknob 45 the horns 46 aEord adequate and convenient means for graspingthe handle 5 and operating the driver.

The magazine 1, the driver plate 6 in part, the wear plate 7, thereceiver plate 8 in part, and the follower 22 are generally similartocorresponding members in application for Letters Patent of the UnitedStates, filed December 29, 1926, Serial No. 157,656.

1n operating the driver the handle 5 is grasped in the hand, said driveris placed at an incline on`a pane of glass, with the front end or noseof the wear plate 7 against the sash or frame member into which thepoints are to be driven, and said handle is forced forwardly with aquick movement to carry the plunger 3 against the lug 12 and the driverplate 6 beneath the open end of the magazine passage 9. This movement isagainst the resistance of the spring 44, and sufficiently forceful andof sufficient length to drive the point 1l, which is on the plate 8 inthe path of the plate 6, into the wood to the required depth. `|rllhenthe plunger 3 is permitted to be retracted by the spring 44, and thedriver is moved to the right or left the required distance and againoperated toforce in the second point 11, and'so ony until the work ofsecuring the pane of glass'with the points is completed. i Each time theplunger 3 and the plate 6 are retracted, a point 11 descends through theopening 20 onto the plate 8.

The recess 27 and the beveled part 28, at the forward terminal of thereceiver plate 8, permit the front end of a point 11 on said plate to belocated very close to the glass when thel driver is positionedready todischarge said point, and to be driven into the wood in actual contactwith the edge of said glass. In the absence of some provision of thiskind, the total'thickness of the plate 8 would intervene between thepoint 11 about to be driven and the glass, and said point could not bedriven close enough to said glass to secure the same in place to thebest advantage, or with a suicient degree of tightness.

The wear plate 7 might be omitted, as shown in Figs. 8 and 9, in whichevent the driver plate 6 operates,v directly in contact with the bottomof the magazine l, and' is guided and supported atthe forward terminalby the plate 8 and its beads 23.

In place of the receiver plate 8, a receiver plate 47 may be employed,which latter plate has'a slightly convex front edge, that correspondsgenerally with the preferred form of the front edge'of the wear plate 7,and Yis beveled cleary across from said first-named edge downwardly andrearwardly, as represented at 48-43-see Figs. 6 and 7.

A receiver plate 49 is illustrated in Figs. 8 and 9, which is straightacross at the front end, but set back some distance from the front edgeof the bottom of the magazine 1, there being no wear plate in thisexample. Thereceiver plate 49 might just as well be used in conjunctionwith a wear plate, in which event it would fall short of or beset backfrom the front edge of the wear plate. With this receiver plate it ispossible to locate the forward end of a point close to and drive thesame in contact with the edge of the glass, as

with the beveled receiver plate. v y

ln the last two views a receiver plate 50 is shown which has its frontedge-locatedsome distance back from the .front edge of the wear plate 7,and the front-edge portion on the bottom beveled downwardly andrearwardly from said edge, as at 51. Thus the receiver plate 50 combinesthe features of the receiver plates 47 and 49.Vv g

It is now seen that, in each and every one of these receiver plates,provision is made' for 'icm driving the points in very close to or incontact with the glass, a procedure which is very essential, not to sayabsolutely necessary, if the glass is to be held in place with therequired degrees of security and tightness.

All of the receiver plates are provided with the beads 21, ears 24,projections 25, and protuberances 26. Y

More or less change in the shape, size, construction, and arrangement ofsome or all of the parts of this driver, in addition to thosehereinbefore specifically pointed out, may be made without departingfrom the spirit of our invention, or exceeding the scope of what isclaimed.l
